Close Call: Line Judge

The ball lands. The mark is there for a moment. The crowd wants a call.

Close Call puts you in the line judge's chair for tennis and pickleball. Watch the mark, then call IN or OUT before the clock runs out. Every call gets a replay that measures the margin to the millimetre.

Know the rules. A mark touching the line by a hair is IN. A pickleball serve that touches the kitchen line is a fault.
